My biggest regret of the "Snoma Speed Festival" weekend was not shooting these super-photogenic cars.  

The "SSF" used a unique scheduling format:  No lunch break. So action was continuous and one had to pick & choose which groups to watch/shoot and which groups to miss (And use their track time to change locations or just rest).

What's a "Ragtime Car"?  I had no idea.  I used their time to do other things.  Late in the weekend I glanced at the track while the "Ragtime Cars" were in action.   Bummer!   I realized that I'd blown it!  The mostly two-man cars were running in a big group and the crews were obviously having a great time.  Wonderful photos missed.  Never again!
